Questo è il migliore che ho visto così lontano che è in grado di utilizzare fuso orario desktop del cliente e modifiche in tempo reale con l'impostazione fuso orario:

//To format string use: timeZoneConvertFormatted("2015-11-03T17:36:20.970")
//November 2, 2015 5:36 PM
//Works even when I change client timezone to Pacific Standard
//Mon Nov 02 2015 15:36:20 GMT-0800 (Pacific Standard Time)

A timestamp unix e timestamp iso non sono la stessa cosa, quindi no, non è un duplicato. – Ian
La data/ora ISO è una stringa? e vuoi analizzarlo in una classe javascript 'Date()'? – jfriend00
